Abstract

The invention relates to the use of one or more polymers chosen from polyethylene glycols, ethoxylated quaternary ammonium compounds and oligoesters, in particular in cosmetic formulations, for stabilizing the color in colored keratin fibers, in particular in human hair, and for protecting these keratin fibers against color loss.

Description

  • The invention relates to the use of polymers for stabilizing the color in colored keratin fibers, particularly human hair, and for protecting against color loss.
  • Colored hair suffers from loss of color during washing. Some cosmetic products attempt to prevent this and to protect the color.
  • EP 509 922 describes the use of polydiorganosiloxane functionalized as thiol.
  • WO 94/07455 describes the use of an active ingredient combination of alkoxylated wool wax alcohols with 1 to 50 molecules of ethylene oxide per alcohol molecule and pyrrolidonecarboxylic acid and/or derivative.
  • DE 197 35 865 describes the use of an aqueous-based composition comprising at least one quaternary ammonium compound, green tea extract and a cationic polymer.
  • EP 940 404 describes the use of at least one organosiloxane which optionally contains at least one group which acts as antioxidant.
  • U.S. Pat. No. 6,143,286 describes a method of color stabilization using a composition which comprises one or more hair-treatment active ingredients and a siloxane with difunctional and trifunctional units.
  • However, the color protection shampoos and hair after-treatment compositions with color protection function in the marketplace are hitherto unsatisfactory. After several hair washes, the hair color is often lost despite using products which claim color protection. In addition, known active ingredients with color protection are often not soluble in water and thus often lead to unstable formulations.
  • It was therefore the object to provide substances which are able to preserve the color in colored keratin fibers, in particular human hair, or to effect protection of colored keratin fibers against color loss, and which do not have the abovementioned disadvantages.
  • Surprisingly, it has now been found that said object is achieved by the following polymer:
    • A) polyethylene glycols of the formula H(OCH2CH2)nOH where n is 150 to 900,
    • B) ethoxylated quaternary ammonium compound of the formula
      Figure US20050138739A1-20050630-C00001

      in which R is C4- to C30-alkyl, x, y and z, in each case independently of one another, are a number from 1 to 300, and X is an anionic counterion, and
    • C) oligoesters which are obtained by condensation of one or more dicarboxylic acids or esters thereof and one or more polyhydric alcohols, optionally in the presence of addition products of an alkylene oxide onto alcohols, alkylphenols or alkylamines, preferably in the presence of methyl polyethylene glycol.
  • The present invention therefore provides the use of one or more polymers chosen from
    • A) polyethylene glycols of the formula (1)
      H(OCH2CH2)nOH  (1),
      in which n is an integer between 150 and 900,
    • B) ethoxylated quaternary ammonium compounds of the formula (2)
      Figure US20050138739A1-20050630-C00002

      in which
    • R is C4- to C30-alkyl,
    • x, y and z, in each case independently of one another, are a number from 1 to 300, and
    • X is an anionic counterion, and
    • C) oligoesters which are obtained by condensation of one or more dicarboxylic acids or esters thereof and one or more polyhydric alcohols, optionally in the presence of addition products of an alkylene oxide onto alcohols, alkylphenols or alkylamines, preferably in the presence of methyl polyethylene glycol, for preserving the color in colored keratin fibers, preferably human hair.
  • Surprisingly, it has also been found that a combination of polymers of two or all three described types of polymer is able to preserve the color in colored keratin fibers, particularly human hair, in a synergistically particularly good way.
  • When using the polymers to preserve the color in colored keratin fibers, in a preferred embodiment of the invention, one or more polyethylene glycols of the formula (1) as in component A) and one or more ethoxylated quaternary ammonium compounds of the formula (2) as in component B) are used.
  • When using the polymers to preserve the color in colored keratin fibers, in a further preferred embodiment of the invention, one or more polyethylene glycols of the formula (1) as in component A) and one or more oligoesters as in component C) are used.
  • When using the polymers to preserve the color in colored keratin fibers, in a further embodiment of the invention, one or more ethoxylated quaternary ammonium compounds of the formula (2) as in component B) and one or more oligoesters as in component C) are used.

L and E values in the CILAB system were determined using a spectrophotometer (Datacolor Mercury 2000). Here, the L values give a measure of the lightness and the E values a measure of the shade. The tresses were then washed four times for one minute in each case with 0.5 ml of standard or test shampoo and rinsed in each case for 30 seconds. L and E values were then measured and the differences determined as DL and DE.
